Shirley June Finn, née Shewring (2 November 1941 – 22 or 23 June 1975), a Perth brothel keeper, nightclub operator and socialite, was shot dead at about midnight on 22–23 June 1975. Her body, dressed in an elaborate ball gown and expensive jewellery, was found at dawn in her car which was parked on a golf course next to a busy freeway. The murder is notable because of Finn's close relationship with Western Australia Police detectives who, in that era, controlled and regulated Perth's prostitution and gambling activities. The crime is unsolved. A coronial inquest held from 2017 to 2020 returned an open finding with an acknowledgement that "it was most likely she was killed because she had tried to blackmail police about corruption."
